The mobile terminal 7 is, for example, a terminal device such as a smart phone, a mobile phone, a personal digital assistant (PDA), and a tablet computer which is used by a user (customer) of the system. The mobile terminal 7 is provided with an application such as a web browser mounted therein for displaying various pieces of information which are provided on the network N5. In addition, a terminal device such as a PC may be used instead of the mobile terminal 7.

The mobile terminal 7 performs a request for a membership registration in the system by accessing the electronic receipt managing server 4 through the network N5. Here, the network N5 is the Internet, or a public network of various types.

Meanwhile, the membership registration of a customer in the system is performed, for example, according to the following order. A customer sends a blank mail to the electronic receipt managing server 4 through the network N5 from the mobile terminal 7. The electronic receipt managing server 4 sends a Uniform Resource Locator (URL) of a page for a membership registration to the received mail address. The mobile terminal 7 displays an input screen for inputting information necessary for the membership registration (name, destination information, or the like) when the customer selects the URL of the page for the membership registration displayed on the mobile terminal 7. After the necessary information is input by the customer, the electronic receipt managing server 4 executes the membership registration with respect to the member master. Thereafter, the electronic receipt managing server 4 delivers a membership registration completion mail including a membership code (customer code) and a password with respect to the mobile terminal 7. In this manner, the membership registration is ended.

After the above described membership registration, as illustrated in FIG. 2, the mobile terminal 7 displays a code symbol CS, such as a barcode or a two-dimensional code, corresponding to the membership code of the customer on a display unit 73. The customer presents the code symbol CS which is displayed on the mobile terminal 7 to a salesclerk when settling a transaction in the store P1. The salesclerk operates a code scanner 15 (shown in FIG. 3) which is connected to the POS terminal 1 to read the code symbol CS which is displayed on the mobile terminal 7. In this manner, it is possible to associate a membership code of a customer with receipt data which is generated after settling due to the merchandise sales data processing in the POS terminal 1.

In addition, the mobile terminal 7 receives an electronic receipt of the transaction which is transmitted from the electronic receipt managing server 4 through the network N5, after the settling (transaction) by the POS terminal 1. After a request for electronic receipt designating a membership code is transmitted to the electronic receipt managing server 4 through the network N5, the mobile terminal 7 receives the electronic receipt of the member from the electronic receipt managing server 4.

Subsequently, operations of each unit which configures the system according to the embodiment will be described.

First, electronic receipt processing which is executed when the control unit 11 of the POS terminal 1 is operated according to the receipt data processing program 17 a will be described with reference to FIGS. 7 to 11.

As illustrated in FIG. 7, when the control unit 11 executes the receipt data processing program 17 a a receipt data generation unit 111 which functions as a receipt data generation unit and a customer code obtaining unit, and a receipt data output unit 112 which functions as an output unit and a conversion unit are generated. As real hardware, when the CPU of the control unit 11 reads the receipt data processing program 17 a from the storage unit 17, and executes the program, the above described each unit is downloaded to the RAM, and the receipt data generation unit 111 and the receipt data output unit 112 are generated in the RAM.

Here, the receipt data generation unit 111 is a functional unit corresponding to an existing application which mainly performs merchandise sales data processing and generates data for printing (receipt data) of a receipt. When obtaining a merchandise code specifying merchandise through the code scanner 15, the receipt data generation unit 111 reads merchandise data corresponding to the merchandise code from a merchandise data file, and executes merchandise sales data processing for calculating a settlement amount based on a unit price which is included in the merchandise data. In addition, the receipt data generation unit 111 generates merchandise sales data which is processed when executing the merchandise sales data processing, that is, receipt data including transaction contents of the merchandise.

In addition, when obtaining a membership code which specifies a customer through the code scanner 15 at any of timings during one transaction, the receipt data generation unit 111 generates receipt data including the membership code.

FIG. 8 is a diagram which schematically illustrates an example of receipt data. Here, the receipt data is non-structured text data, or the like, and is used in a printing by the printer 13. As illustrated in FIG. 8, the receipt data includes elements of the above described merchandise sales data D1 and a membership code D2. Here, the merchandise sales data D1 includes a merchandise name (merchandise code) of merchandise as a settlement target, an amount of money thereof, a total amount of all merchandises, a deposit amount which is paid by a customer, a change amount, or the like.

In addition, the receipt data includes elements of a company code (company name) D3 denoting a company which operates a store, a store code (store name) D4, a telephone number of a store D5, an address D6, a transaction date and time D7, a transaction number (receipt number) D8, a register number D9, a name of a person in charge D10, and the like. In addition, elements which are included in the receipt data are not limited to the example shown in FIG. 8, other elements such as business type and business category codes may be included, and elements such as the telephone number D5, the address D6, or the like, may be excluded.

In addition, when the settlement key is pressed down, the receipt data generation unit 111 determines that merchandise sales data processing of one transaction is completed, and outputs (issues) generated receipt data to the receipt data output unit 112 along with a cut command. Here, the cut command is one of generally-used control commands for a printer, and is command information for commanding cutting of a sheet on which an image corresponding to the receipt data is printed. In addition, the receipt data may be collectively generated along with pressing of the settlement key, or may be sequentially generated, every time a merchandise code or a customer code is obtained.

The receipt data output unit 112 determines an output destination of the receipt data every time receipt data of one transaction is generated by the receipt data generation unit 111. More specifically, when the cut command is issued by the receipt data generation unit 111, the receipt data output unit 112 determines that receipt data of one transaction is generated. In addition, the receipt data output unit 112 determines whether or not a membership code is included in the generated receipt data, and outputs the receipt data to an output destination which is determined according to a determination result thereof.

Specifically, when determining that a membership code is not included in the receipt data, the receipt data output unit 112 outputs the receipt data to the printer 13 along with the cut command. In this manner, the printer 13 prints out a paper receipt of one transaction by cutting a sheet thereof according to the cut command after printing the receipt data on the sheet. In addition, at a time of printing out, all of elements configuring the receipt data may be printed, a membership code, or the like, may be excluded, or printing may be performed in a state in which other information such as an advertisement, or the like, is added.

In addition, when determining that the membership code is included in the receipt data, the receipt data output unit 112 converts the receipt data into a predetermined data format according to the conversion rule of the receipt data schema 17 c. In addition, the receipt data output unit 112 transmits (outputs) the receipt data of which the data format is converted, i.e., an electronic receipt, to the electronic receipt server 3 which is managed by the company corresponding to its company code.

Here, FIG. 9 is a diagram which schematically illustrates an example of an electronic receipt. As illustrated in FIG. 9, the electronic receipt includes structured data (structured document) such as data of XML or CSV format. FIG. 9 illustrates an example in which each element (D1 to D10) of the receipt data illustrated in FIG. 8 is converted into an XML format.

A conversion of receipt data into an electronic receipt is performed based on the conversion rule which is described in the receipt data schema 17 c. Specifically, in the receipt data schema 17 c, predetermined elements configuring the receipt data, and attribute information (tag, or the like) denoting an attribute of each element are defined. The receipt data output unit 112 generates a structured electronic receipt as illustrated in FIG. 9 by causing each element of the receipt data to be structured using corresponding attribute information. Since the elements which are included in the electronic receipt may be efficiently used by generating the structured electronic receipt in this manner, it is possible to obtain various advantages when managing data.

In this manner, the receipt data output unit 112 determines that receipt data of one transaction is generated when the cut command is issued by the receipt data generation unit 111, and starts an output of the receipt data. In this manner, since it is not necessary to transmit to the receipt data output unit 112 an additional signal for commanding an end of one transaction from the receipt data generation unit 111, the receipt data output unit 112 can perform the output of the receipt data of one transaction without a special change with respect to the receipt data generation unit 111 corresponding to an existing application. In addition, since a change of the receipt data generation unit 111 may be unnecessary, it is possible to execute an electronic receipt output function while using the existing application efficiently.

In addition, the receipt data output unit 112 determines the output destination of the receipt data depending on whether or not the membership code is included in the receipt data. In this manner, since an output of a paper receipt or an electronic receipt may be performed without preparing information on whether or not the paper receipt is necessary with respect to each customer, it is possible to efficiently determine the output destination of the receipt data. In addition, for example, since a customer (member) may select an output of the paper receipt or the electronic receipt by inputting or not inputting the membership code in each transaction, it is possible to improve convenience of the customer.

In addition, when outputting the receipt data to the electronic receipt server 3, the receipt data output unit 112 converts the receipt data into an electronic receipt in which the elements which are included in the receipt data are structured, and outputs the electronic receipt. In this manner, since the elements which are included in the electronic receipt may be efficiently used, it is possible to improve convenience of the electronic receipt in the electronic receipt server 3 and the electronic receipt managing server 4 which manage the electronic receipt, or in the mobile terminal 7 which performs a display of the electronic receipt.

FIG. 10 is a flowchart which illustrates a flow of a process of the electronic receipt in the POS terminal 1. First, the receipt data generation unit 111 of the POS terminal 1 determines whether or not a code symbol (merchandise code) which is attached to merchandise, or a code symbol (membership code) which is displayed on the mobile terminal 7 is read by the code scanner 15 (Step S11). When the code symbol is not read (No in Step S11), the receipt data generation unit 111 proceeds to Step S16.

On the other hand, when it is determined that the code symbol is read (Yes in Step S11), the receipt data generation unit 111 determines whether information which is obtained through the reading is a merchandise code or a membership code (Step S12).

When it is determined that the merchandise code is obtained in Step S12 (Step S12; merchandise code), the receipt data generation unit 111 executes merchandise sales data processing for calculating a settlement amount, based on a unit price which is included in merchandise data, when the merchandise data is read from a merchandise data file with respect to merchandise which is specified by the merchandise code (Step S13). Subsequently, the receipt data generation unit 111 generates receipt data including merchandise sales data which is processed when performing the merchandise sales data processing (Step S14).

In addition, when it is determined that the membership code is obtained in Step S12 (Step S12; membership code), the receipt data generation unit 111 generates receipt data including the membership code (Step S15).

Here, in order to input the membership code to the POS terminal 1, for example, a customer displays a code symbol including a membership code, or the like, on the display unit 73 of the mobile terminal 7, and a salesclerk or the customer reads the code symbol using the code scanner 15 of the POS terminal 1. In addition, the receipt data generation unit 111 may have a configuration in which an exclusive process, or the like, in which a membership code which is input during one transaction becomes the only code is performed.

In subsequent Step S16, the receipt data generation unit 111 determines whether or not a start of a settlement processing is commanded by the pressing down of the settlement key or the like (Step S16). When the start of the settlement processing is not commanded (No in Step S16), the process returns to Step S11. When the start of the settlement processing is commanded (Yes in Step S16), the receipt data generation unit 111 issues (outputs) a cut command to the receipt data output unit 112 (Step S17).

When receiving the cut command from the receipt data generation unit 111, the receipt data output unit 112 determines that receipt data of one transaction is generated, and determines whether or not a membership code is included in the receipt data (Step S18).

When a membership code is not included in the receipt data (No in Step S18), the receipt data output unit 112 performs printing out of the receipt data by outputting the receipt data of one transaction along with the cut command to the printer 13 (Step S19), and the process is ended. In this manner, the printer 13 performs printing out of a paper receipt of one transaction by cutting a sheet according to the cut command after printing the receipt data on the sheet.

On the other hand, when the membership code is included in the receipt data (Yes in Step S18), the receipt data output unit 112 generates an electronic receipt by converting a data format of the non-structured receipt data into structured format (Step S20). In addition, the receipt data output unit 112 transmits the electronic receipt which is generated through the communication I/F 16 to the electronic receipt server 3 (Step S21), and the process is ended.

In addition, in the above described processing, when the membership code is included in the receipt data, the receipt data is output to the electronic receipt server 3. However, it is not limited to this, and the receipt data may be output to both the printer 13 and the electronic receipt server 3.

In addition, an output destination of the receipt data may be selected when the membership code is included in the receipt data. For example, the mobile terminal 7 may cause the code symbol CS which will be displayed to include output classification information for designating an output destination of the receipt data, and the output destination can be determined based on the output classification information. In this case, the receipt data generation unit 111 includes the output classification information, which is read by the code scanner 15, in the receipt data along with the membership code. In addition, when it is determined that the membership code is included in the receipt data and that the output classification information is present, the receipt data output unit 112 determines an output destination of the receipt data based on the output classification information. In addition, it is possible to designate anyone of the printer 13 and the electronic receipt server 3, or both of the printer 13 and the server 3 in the output classification information.

In addition, an output destination of receipt data may be selected every time a settlement of merchandise is made. In this case, for example, when it is determined that a membership code is included in receipt data, the receipt data output unit 112 displays an output destination selection screen for selecting an output destination of the receipt data on the display unit 14.

Here, FIG. 11 is a diagram which illustrates an example of an output destination selection screen G1 which is displayed on the display unit 14. As illustrated in FIG. 11, the output destination selection screen G1 includes a first button B1 which designates the printer 13, a second button B2 which designates the electronic receipt server 3, and a third button B3 which designates both the printer 13 and the electronic receipt server 3 as operational buttons which designate an output destination of receipt data. When using the output destination selection screen G1, an operator of the POS terminal 1 asks a customer about an output destination of receipt data, and operates one of the buttons corresponding to the output destination selected by the customer. In addition, when receiving the operation of the operator, the receipt data output unit 112 outputs the receipt data to an output destination corresponding to the selected button.

In addition, a display of a selection screen is not limited to the display for operator 14 a, and may be displayed on the display for customer 14 b. In addition, when the display for customer 14 b is configured of a touch panel, a customer himself may select an output destination.

In addition, a customer may confirm the output destination of the receipt data during the merchandise sales data processing, and in such a case, the receipt data generation unit 111 displays the output destination selection screen G1, or the like, on the display unit 14, and the output destination corresponding to an operated operator is included in the receipt data as output classification information. In addition, when the membership code and the output classification information are included in the receipt data, the receipt data output unit 112 determines the output destination of the receipt data based on the output classification information.

In this manner, when the membership code is included in the receipt data, the receipt data output unit 112 receives a selection of the output destination of the receipt data automatically or manually. In this manner, since a method of determining the output destination may be flexibly switched, it is possible to efficiently determine the output destination of the receipt data.

Subsequently, a flow of electronic receipt managing processing which is executed when the control unit 31 of the electronic receipt server 3 is operated according to the electronic receipt managing program 33 b, and a flow of information transmission processing which is executed when the control unit of the electronic receipt server is operated according to the information transmission program 33 c will be described with reference to a flowchart illustrated in FIG. 12.

When receiving an electronic receipt which is transmitted from the POS terminal 1 through the communication I/F 32 (Yes in Step S31), the control unit 31 of the electronic receipt server 3 stores the electronic receipt of a company in the electronic receipt managing region 33 a of the storage unit 33 (Step S32). In addition, the control unit 31 of the electronic receipt server 3 transmits the electronic receipt which is stored in Step S32 to the electronic receipt managing server 4 (Step S33), and the process returns to Step S31.

In addition, at a preset transmission timing (No in Step S31→Yes in Step S34), the control unit 31 of the electronic receipt server 3 transmits the electronic receipt which is stored and managed in the electronic receipt managing region 33 a to the electronic receipt managing server 4 (Step S35), and the process returns to Step S31. By the transmission in Step S35, it is possible to transmit an electronic receipt which is omitted from transmission targets in Step S33, for example, to the electronic receipt managing server 4. In addition, in Step S35, a control of transmitting only a non-transmitted electronic receipt may be possible.

Subsequently, a flow of electronic receipt managing processing which is executed when the control unit 41 of the electronic receipt managing server 4 is operated according to the electronic receipt managing program 43 c, and a flow of merchandise information transmission processing which is executed when the control unit of the electronic receipt managing server is operated according to the information transmission program 43 d will be described with reference to a functional block diagram illustrated in FIG. 13, and a flowchart illustrated in FIG. 14.

As illustrated in FIG. 13, when the control unit 41 executes the electronic receipt managing program 43 c and the information transmission program 43 d, a module configuration including a reception unit 411 which functions as a reception unit, an electronic receipt managing unit 412, and an electronic receipt transmission unit 413 is generated. As real hardware, when the CPU of the control unit 41 reads out the electronic receipt managing program 43 c and the information transmission program 43 d from the storage unit 43, and executes the programs, each above described unit is loaded to the RAM, and the reception unit 411, the electronic receipt managing unit 412, and the electronic receipt transmission unit 413 are generated in the RAM.

The reception unit 411 includes a company code which denotes a company operating a store, and receives a receipt which is printed and issued at a time of merchandise sales data processing, or an electronic receipt on a company basis which is electronically processed instead of the receipt, from the electronic receipt server 3.

The electronic receipt managing unit 412 stores the electronic receipt on the company basis which is received by the reception unit 411 in the electronic receipt managing region 43 a of the storage unit 43, and manages the electronic receipt. In addition, the electronic receipt managing unit 412 stores additional information such as promotion information related to a promotion program which is correlated with a desired merchandise and elements of specific conditions (for example, limiting to specific company which operates a store, limiting to specific region, limiting to specific time, or the like) in the additional information managing region 43 b of the storage unit 43, and manages the additional information.

The electronic receipt transmission unit 413 obtains an electronic receipt which is correlated with the membership code, and includes one or more company codes from the electronic receipt managing region 43 a, and transmits the electronic receipt to the mobile terminal 7 which is correlated with a membership code of a predetermined shopper. In addition, when additional information is correlated with the elements configuring the electronic receipt, the electronic receipt transmission unit 413 obtains the additional information from the additional information managing region 43 b, and transmits the additional information to the mobile terminal along with the electronic receipt.

As illustrated in FIG. 14, the reception unit 411 of the electronic receipt managing server 4 determines whether or not the electronic receipt which is transmitted from the electronic receipt server 3 in each company is received through the communication I/F 42 (Step S41).

When it is determined that the electronic receipt is received (Yes in Step S41), the electronic receipt managing unit 412 of the electronic receipt managing server 4 stores the electronic receipt of each company in the electronic receipt managing region 43 a of the storage unit 43 (Step S42). Here, when there is additional information which is associated with elements of stored electronic receipt (merchandise code, membership code, company code, store code, or the like), the additional information is correlated with the elements. Subsequently, the electronic receipt transmission unit 413 transmits the electronic receipt which is stored in Step S42 to a transmission destination (mobile terminal 7) which is managed by being correlated with a membership code of the electronic receipt (Step S43), and the process returns to Step S41. In addition, in Step S43, when additional information is correlated with the electronic receipt, the additional information is also transmitted to the transmission destination.

In addition, when there is an inquiry of an electronic receipt from the mobile terminal 7 (No in Step S41→Yes in Step S44), the electronic receipt transmission unit 413 of the electronic receipt managing server 4 extracts an electronic receipt which is stored and managed in the electronic receipt managing region 43 a according to contents of the inquiry of the electronic receipt (Step S45), and then transmits the electronic receipt to the mobile terminal 7 which made the inquiry (Step S46), and the process returns to Step S41. In addition, in Step S46, when additional information is correlated with the electronic receipt, the additional information is also transmitted to the mobile terminal 7 which made the inquiry.

Subsequently, a flow of electronic receipt reception processing which is executed when the control unit 71 of the mobile terminal 7 is operated according to an electronic receipt correspondence program 75 a, and a flow of electronic receipt reading processing which is executed when the control unit of the mobile terminal is operated according to an electronic receipt reading program 75 b will be described with reference to FIGS. 15 to 17.

As illustrated in FIG. 15, the control unit 71 executes the electronic receipt correspondence program 75 a and the electronic receipt reading program 75 b, a module configuration including a member correlating unit 711, an electronic receipt reception unit 712, and an electronic receipt display unit 713 is generated. As real hardware, when the CPU of the control unit 71 reads out the electronic receipt correspondence program 75 a and the electronic receipt reading program 75 b from the storage unit 75, and executes the programs, each above described unit is loaded to the RAM, and the member correlating unit 711, the electronic receipt reception unit 712, and the electronic receipt display unit 713 are generated in the RAM.

The member correlating unit 711 causes the mobile terminal 7 and a membership code of a predetermined shopper to be correlated with each other. The electronic receipt reception unit 712 receives an electronic receipt from the electronic receipt managing server 4. The electronic receipt display unit 713 causes the electronic receipt which is received by the electronic receipt reception unit 712 to be displayed on the display unit 73.

As illustrated in FIG. 16, first, the member correlating unit 711 of the mobile terminal 7 executes authentication processing by accessing the electronic receipt managing server 4 in response to input of a membership code and a password (Step S51). In this manner, the mobile terminal 7 and the membership code of the predetermined shopper are correlated with each other.

After the authentication, the electronic receipt reception unit 712 of the mobile terminal 7 receives an electronic receipt which is stored and managed in the electronic receipt managing region 43 a of the electronic receipt managing server 4 by corresponding to the input membership code (Step S52). In addition, when additional information is correlated with the electronic receipt, the additional information is also received from the electronic receipt managing server 4. In addition, receipt data may be received through an email.

Subsequently, the electronic receipt display unit 713 of the mobile terminal 7 causes the electronic receipt, or the like, which is received by the electronic receipt reception unit 712 to be displayed on the display unit 73 (Step S53), and the process is ended.

FIG. 17 is a diagram which illustrates an example of an electronic receipt G2 which is displayed on the display unit 73 of the mobile terminal 7. The electronic receipt G2 is displayed with the same layout or contents as that of a receipt which is printed on a sheet. In addition, in the electronic receipt G2, it is possible to focus on merchandise “a”, or the like, denoting a transaction merchandise, using a cursor which is subject to an input of the operation unit 72. In addition, FIG. 17 shows an example in which a store name logo portion G21 at which a logo of a store name is displayed, and a banner display portion G22 at which an advertisement, or the like, is displayed are provided in the electronic receipt G2.

In addition, a display format of receipt data does not necessarily match an image of a receipt which is printed on a sheet. However, the receipt data substitutes for a paper receipt, and is electronic merchandise purchase certification information which certificates purchasing of merchandise. Therefore, since the receipt data is used in a case of being presented as the merchandise purchase certification information in FIG. 17, an example in which the following information is displayed is illustrated.

-   -   store name     -   purchase date and time     -   specification of purchased merchandise     -   total sales amount     -   deposit amount     -   change amount     -   register number     -   transaction number

Here, when a URL (access information) of the promotion managing server 6, or the like, is set as additional information of any of the merchandise “a”, the hyperlink is embedded in a corresponding merchandise name, or an icon b, or the like, as an operator for commanding access to the URL is displayed.

For example, when the access destination which is denoted by the URL is a server device which receives an access to a predetermined campaign (for example, promotion managing server 6), the control unit 71 of the mobile terminal 7 accesses the promotion managing server 6 according to pressing down of the icon b, or the like, and displays information of the campaign. A membership code of own apparatus which is included in receipt data, or the like, may be transmitted when accessing an access destination. In addition, in the promotion managing server 6, an access history in each type of campaign is managed by being correlated with a membership code for identifying each member.

In addition, when receiving a plurality of pieces of receipt data, a selection screen from which each piece of receipt data may be selected based on a purchase date, a company code, or the like, which is included in the receipt data may be displayed. In this case, the electronic receipt display unit 713 causes receipt data which is selected from the selection screen to be displayed on the display unit 73.
